How to fix an iPhone CPU - Full Transfer for Data Recovery

- It is great to want to learn microsoldering, but you DO NOT PRACTICE ON CUSTOMER DATA JOBS. A shop in Florida (who I shall not name), decided to try their luck on this water damaged iPhone 12 pro max. They were unable to split the sandwich and they overheated the CPU. When this customer called me, she was desperate and crying because she wanted her baby photos so badly. When I told her that the last shop overheated the CPU and potentially killed her board, she was devastated. I very much hate having my customers cry.
The worst part about it is that this would have been an extremely easy job had it not been touched by an amateur board tech.
It is even likely that this was THE 5G ANTENNA and didn't even really need board work.
This is why it is so important to learn how to properly diagnose, rather then just going straight to your worst assumption. I often preach diagnosis over CPU swaps, etc. But that also applies to simpler things like board splits, especially if you are an amateur.
There are a lot of resources for learning microsoldering nowadays. That has its benefits but also its drawbacks. In many ways, it has given the false assumption that anyone can do microsoldering when I don't really believe that is the case. It takes a particular type of person to really become a master at microsoldering. It is also not a quick or easy thing to do.
People think that if they spend $2k+ going to a week long course, and then another $2k buying equipment then they have everything they need to do the work. That is not the case.
YOU NEED PRACTICE.
Some people have only a few hours under their belt before they start taking customer jobs. Some people have 30 or 40 and think that is good enough.
Conservatively, I would say I solder about 4 hours a day, 5 days a week. Some weeks it is much more, but there have been times it is less. That is 20 hours a week. But that is every week for the last 7 years. That is 1000 hours a year, or 7000 hours over the last 7 years.
When people ask how I know what to do, or why I don't mess stuff up, it is because I have put in that time. So again I will say:
YOU NEED PRACTICE.
I bought my own water damaged devices and painstakingly tried to figure out what I was doing for an entire year before I ever touched customer devices. That is because I didn't want to ruin other people's property.
Anyways, sorry for the long rant. It is just sad to know that many wannabe techs ruin boards when they should have had the foresight to know that it is not as easy a pros make it look.
In this video, I fix the mistake of the last technician with a CPU swap and I secure the data for this grateful customer.

i watched a few of your videos and think u explain things well i'm new to this about a yr and a half i done through hole soldering and sm back in school porter & chester learnning computer electronics, went to pitney for about 17 yr, pm machiens, learning the ipads, but this is very interesting i have watched videos so much to get what i can from them, hours and hours and more hours going back and a very lot of notes, i went deep in this hobbie and now need to learn more, thank you and to all who take the time to support the customer they keeps us going
Thanks for watching, happy to help!
My man! Keep up the good work.
Also good to hear from you bro! Thanks for the support!
you are good person. great work.
On minute 44:17 was scary when the eeprom blow up. Thanks GOD you got the eeprom on the tower. Good video
Lol yes that was scary. I would have had to search for awhile otherwise. I use low air during that part. But still, I should not let that happen.
Excellent work !
Thanks for watching!
great work.
Awesome job ❤️
Thanks for the support Isaias!
great work and vid
Good job 👏
thanks aaron
Nice job 👌👍❤️
BTW r u work from home?
Your daughter is so cute 🥰
Is the old board reusable by uv curing ?.
What happened there.
Peeled of pcb layer?
It's an extremely difficult job. I wish I were at your level
For cleaning the cpu undefiled what temp plz master am using Quick 861
hi can you share your temp and air in hot air for reference, and also the brand of you reballing stencil it very precise...thanks
I change my temps a lot. Usually I remove cpu around 370c with 75 air. But I am not firm with my temps. I use this stencil: www.unionrepair.com/maant-c1-magnetic-motive-reballing-stencil-platform-for-a8-a16.html
@@iBoardRepair thank you keep on sharing, learning a lot from you
Hi Aaron what is the CPU holder and stencil you are using please?

Next time please mention about the temperature and air at the side of screen for reference n educational purposes
I change my temps a lot. Usually I remove cpu around 370c with 75 air
How did you power up the phone? Was that the positive lead of the DC power supply?
Also, what do you connect to the phone to get to the data? And how?
I am not sure at which point you are referring to, but at the end of the video I powered it with a battery. I just connect to pc to pull data. There are a lot of software that can parse it, or you can just pull an itunes backup. I may make a video one day about the software I use, but they are nothing special and there are many different methods that different people use.
@@iBoardRepair After watching Jesse's video I believe you just used the charging cable to boot the phone. That's what I was asking about at the 53 or 54 mark
Im having issues improving my reballing skills, when taking out CPU I loose pads on CPU itself and not on the board. I use a SUGON 8620DX. Heat 380°C and Air flow 30... Pls are there any recommendation or Guide u can give to me?????
I think you need to add a bit more airflow something at least 60
What solder paste do you use to reball iPhone 12 & 13 sandwich board?
148c, but 138 or even 183 would probably be okay too. It is just personal preference.
I think that beautiful little girl want to heat CPU again😂😂 but well done bro you are my inspiration ❤
Appreciate that bro!
sir please I need help. I have an iphone 12 pro max and sometimes appears like pink squares for only a second and when I try to play pubg mobile it crashes so much like every 3 minutes less or more it keeps crashing again all the time, and I'm not able to bring it back to apple for many resons. Can you help me with an app on the macbook or PC to solve this problem without opening iphone hardware parts ?
It most likely needs new parts and software won't help
What stencil did you use for the CPU reballing?
I use Qianli stencils
Is it possible to upgrade the AP?
Not possible.
Wish you had shown how to unsandwich the logic board
I assume if you are going to be attempting any type of cpu work, then you should already have the splitting skill down perfectly. Otherwise, there is zero chance at a successful cpu swap. Most of my other videos show the split, but it is very simple. Put on a heating platform, then pull apart when it is the appropriate temp.
@@iBoardRepair I saw how to do it in VCC video with a heater, etc...thanks
What's the jig you use

@@iBoardRepair thank you for the link
Beautiful daughter ❤️❤️❤️😘😘😘
Maybe they heating it with stove
😂
brother
55:00 hi...
She says hi!
@@iBoardRepair 🥰
only luck to remove cpu
I am so lucky I put in thousands of hours of practice

Thanks bro!
How much heat and air have you used to remove the cpu! You are not here to teach you are just making your content
Right.

@@iBoardRepair thanks a lot man. I really appreciate. Watched your video and it does reball well. Please what solder paste do you also use to reball I phone 12 and 13 series sandwich board?
